Shaofeng SHI commented on KYLIN-967:
------------------------------------
As recently some bad query crashes Kylin server, we decides to let
BadQueryDetector kill long running queries (>5 mintues) when low memory occurs
(avialable mem < 100M).
> Dump running queries on memory shortage

> Project: Kylin
> Issue Type: Bug
> Reporter: liyang
> Assignee: liyang
> Fix For: v2.0, v1.1
>
>
> Encountered high GC in Kylin query service sometimes. Suspect some bad query
> is taking up too much system resource.
> The feature should dump running queries on resource shortage. Then
> troubleshoot can proceed. Optionally, bad query can be killed once detected.
